Hi Laszlo,
Please check attachment.
debug-exclusive.log: open SNP with exclusive, IPv6 PXE booting fails in
grub2 and falls into grub rescue mode immediately. (no freeze).
debug-no-exclusive.log: open without exclusive, IPv6 PXE booting succeed
into normal mode and can see the boot menu.
I didn't see freeze this time, maybe because I rebuilt OVMF from different
version.
The debug mask bits was set to
gEfiMdePkgTokenSpaceGuid.PcdDebugPrintErrorLevel|0x8040404F
(added version + net to default mask).
But interestingly, I didn't see much difference in the logs, probably
debug output not really enabled ?
Thanks.
